So each campaign "quest" has Normal and Hard difficulty settings, although as a person new to console shooters, I still find Normal fairly difficult at times -- mostly at the boss portion at the tail-end. I understand that these spots are supposed to be challenging, but I end up dying frequently and becoming frustrated. I enjoy the game a lot, but would rather play through it on easy, level up a tad and get used to it, and replay on harder settings. Thanks.
